| Title | Sole Irofs Pressure Mat Did Not Function as Designed |
| Event Description | During a post maintenance test of a sole IROFS (Item Relied On For Safety) in the scrap press area, it was discovered that a sole IROFS of a pressure mat did not function as designed. The pressure mat is designed to ensure operator presence. The clutch that would be disengaged when the pressure switch is not active failed to do so. The press was immediately shut down. Similar presses have also been shut down. Double contingency was maintained (Moderation and Mass). The sole IROFS is designed for prevention of a fire scenario. At no time was an unsafe condition present.
There were no radiological or chemical hazards resulting from this event. The licensee is conducting an investigation to determine the cause of the failure. The licensee has notified NRC R2 Inspectors and State and Local Agencies. |
